Plastic bags have either been charged or banned in more than 60 countries around the world. Charging for plastic bags as demarketing practice in Turkey is quite new. The aim of this study is to reveal the relationship among attitude toward reducing the use of plastic bags, environmental attitude and environmental behavior within the framework of the law ratified on January 1, 2019. In order to classify consumers, two dimensions of environmental attitude; ecocentric attitude and anthropocentric attitude were used. The structural equation modeling (SEM) was also used to determine the relationships between latent variables and data analyzed based on path analysis on a sample of 406 responses from Denizli, Turkey. According to the findings of this research, there are statistically significant differences between ecocentric attitude and environmental behavior; environmental behavior and attitude toward reducing the use of plastic bags. In addition, the results revealed that in the attitude toward reducing the use of plastic bags, statistically significant differences were found based on gender, marital status and age in terms of individuals aged 30 and over.

This paper reports the results of a case study of the application of the microtremor exploration method in western Turkey. We have conducted microtremor surveys at strong motion stations in Aydin and Denizli provinces to derive shallow S-wave velocity profiles. Array records of vertical microtremor motion were acquired at 12 and 15 stations in Aydin and Denizli provinces, respectively. A spatial autocorrelation analysis was applied to the records to estimate Rayleigh wave phase velocities in the frequency range of 3–30 Hz. Then, the phase velocity dispersion at each station was inverted to a one-dimensional S-wave profile down to a maximum depth of about 50 m. The soil models at 5 and 11 stations in Aydin and Denizli provinces, respectively, have a bedrock with an S-wave velocity of 400–600 m/s at depths less than 10 m. The spatial distribution of average S-wave velocities in the top 30 m of the revealed profiles shows low values in the Büyük Menderes Graben and the Denizli Basin, and high values in the surrounding hill or mountain areas. We compared our S-wave profiles with those from previous surface-wave studies. S-wave velocities in shallow parts to a depth of 5–10 m are similar in the two studies. However, S-wave velocities in deep parts are different at some of the stations. [ABSTRACT FROM AUTHOR]

Huntite, a naturally occurring carbonate mineral, originates through the alteration processes of dolomite and magnesite. While its structural characteristics align with typical carbonate minerals, its distinction arises from its polyhedral conjunctiveness. The versatile utility of huntite spans several industries, including paint, flame retardant, plastic, polymer, and pharmaceutical sectors. Noteworthy among its diverse applications is its utilization as a flame-retardant additive in raw materials. In this investigation, three samples received from the Denizli region of Turkey were subjected to detailed analysis followed by an enrichment process involving mechanical attrition and sieving of 38 microns where undersize products were obtained, exhibiting 86.9% huntite for the H-1 sample and 91.9% huntite for the H-2–3 sample. The huntite concentrates were then incorporated into paint formulations with the objective of enhancing flame retardancy. A series of testing protocols were implemented to assess the quality of the resulting paints, ultimately yielding a fire-resistant paint formulation through utilizing the H-1 sample.

One of the first applications for teacher training, which was seen as the locomotive of development and progress, was the issue of training village teachers. In line with this aim, the first village teacher training school was opened in September 1926 in the town of Zincidere in Kayseri. Another village teacher training school was opened in Denizli in 1927. In Turkey, many teachers were trained in just 6 years of education, and these teachers worked in the remotest corners of the country. In line with the possibilities of the period, both theoretical and practical education was provided at the village teacher training schools, which set an example for the Village Institutes to be opened later. This research, which is an examination of the decision book of the Kayseri Zincidere Village Teacher Training School Council (1929-1932), is a qualitative study and was framed with the content analysis technique. Although the school opened in 1926, the existing decision book (1929-1932) was analyzed because the book belonging to the first years of the school could not be reached. Because of the examination, it was seen that topics such as "status of one-month education, actions to be followed, disciplinary situation, books and stationery, instructions, examinations, curriculum program, discussion of one of the lessons", which will set an example for today's teachers' council, were emphasized. In addition, in line with the information obtained, the structure, functioning, and practices of the teachers' boards of that period also lead to the idea that the issues discussed are more effective and efficient than the structure, functioning, and practices of today's teachers' boards.

In recent years, increasing the rate of green energy use in order to meet the increasing energy demand and combat global warming has become one of the important goals of the countries. For this reason, the integration of renewable energy sources as distributed generation has become increasingly popular. In this study, hybrid renewable energy systems were designed for the electrification of a 100-household area in the Sarayköy district of Denizli province, Turkey, and the Hybrid Optimization Model for Electric Renewables program was used to optimize the required component outputs to to achieve the best economic and environmental results. A total of six hybrid renewable energy system designs, three grid-connected and three stand-alone, were created with different combinations of components such as photovoltaic panel, wind turbine, diesel generator, battery energy storage system, and converter. The most economical design was the grid-connected system with only solar energy with a unit energy cost of 0.0362 $/kWh, while the most cost-effective was the stand-alone system containing solar energy, wind energy, and batteries with 1.61 $/kWh. In terms of the environment, on the contrary, off-grid systems emit less carbon dioxide, while on-grid systems emit more carbon dioxide. [ABSTRACT FROM AUTHOR]

An earthquake of M = 5.6 occurred on the March 20, 2019, in Acipayam, Denizli, located in a seismically active area at the southwest Anatolian fault system, in Türkiye. It caused extensive damages of infrastructures. The relevant fault (Acipayam–Serinhisar fault zone) has not shown on the active fault map of Türkiye, and it has been discovered first time by this study. The earthquake occurred on the Acipayam segment of this fault zone, which is divided into two separate segments. Three trenches were excavated for paleoseismological studies on this segment. The samples collected from the trenches were dated by radiocarbon method. The obtained data proposed three seismic events, which caused a surface rupture, at BC 235–95, AD 1227–1263 and AD 1471–1738. Considering the last two events, this fault segment produced two earthquakes of magnitude 6.0 and 6.5, 350 years apart. [ABSTRACT FROM AUTHOR]

Various machine learning (ML) techniques have been recommended and used in the literature to produce landslide susceptibility map (LSM). On the other hand, feature engineering (FE) is an important topic in ML studies, but the concept is ignored by most research. In this study, a novel FE framework, including feature selection, feature transformation, feature binning, and feature weighting, is proposed to produce LSMs using eXtreme gradient boosting (XGBoost), random forest (RF), and support vector machine (SVM). For this purpose, first, thirteen landslide conditioning factors used in data preprocessing were utilized for producing LSM models in the study area, Babadag district of Denizli Province in the Aegean region of Turkey. Second, two irrelevant factors eliminated from the input feature subset using the feature selection in the FE framework. Third, features determined as skewed data were converted into symmetric form by applying feature transformation analysis with log transformation. Then, the remaining factors having continuous values were turned into categorical values using the quantile classifier technique. During the feature weighting phase, four different feature weighting methods, namely, eXtreme Gradient Boosting, random forest (RF), non-negative least squares (NNLS), and Frequency Ratio, were utilized to calculate the weights in each subclass of each landslide-related factor. In addition, the proposed feature subsets were also compared with raw data. At the end of process, the XGBoost model constructed with a FR-selected subset (Overall Accuracy (Acc) = 0.907 and area under curve (AUC) = 0.9822) outperformed both raw (Acc = 0.874; AUC = 0.960) and other methods (i.e., RF–FR and SVM–NNLS). Consequently, the study results revealed that the proposed FE approach could be a useful framework to increase the performance of ML techniques in identifying and extracting relevant features to develop highly optimized and enriched models.

DIATOMACEOUS earth ,GRAIN size - Abstract
Diatomite needs to go through the flux-calcination process in order to increase its functionality in some specific applications such as filter aids. In this study, the effects of the thenardite, which was used for the first time as a flux in the calcination of diatomite, and widely used soda ash on the industrially important physico-chemical properties of diatomite were investigated. Samples taken from two diatomite deposits in the Aegean region of Turkey (Seydiler diatomite from Afyon and Sarayköy diatomite from Denizli) were used in this study. In raw and calcined diatomite samples, geochemical and mineralogical composition and parameters such as colour, grain size, morphology, specific surface area, permeability and wet cake density were characterized. It was found that thenardite was more effective than traditionally used soda ash in improving whiteness (L* = 98.20) and filtrate clarity (wet cake density = 0.378 g/cm
3 ). However, higher permeability (k), i.e., higher filtration rate, was obtained in diatomite calcined with soda ash (k = 0.97 µm2 ). Fluxes had different effects on different diatomite species. The necessity of choosing flux type depending on the application area and the desired properties from diatomite was demonstrated. [ABSTRACT FROM AUTHOR]- Published

This study aims to examine the prediction of the mushroom-type management approach on the loneliness levels of the employees and organizational charlatan behaviors in schools. There is no study investigating the relationship between these variables and studies examining the relationship of these variables with other variables are limited. Thus, this study aimed to fill the gap in the literature. The research was designed in a relational screening model and was carried out in the province of Denizli in Turkey with 464 participants. In the research, the mushroom type management scale, UCLA loneliness scale-3, and organizational charlatan scale were used. Validity and reliability studies of the mushroom-type management scale for schools were reconstructed. UCLA loneliness scale-3 and organizational charlatan scales were adapted to Turkish by the researcher. Data were collected with the help of electronic forms. Regression analysis was carried out to determine the extent to which mushroom type management predicted teachers' organizational loneliness behaviors and teachers' organizational charlatan behaviors. Results demonstrated that mushroom management positively affects the two variables; therefore, school principals should avoid mushroom-type management behavior in order not to push his/her teacher towards charlatanism or loneliness.
